Israel carried out airstrikes on Hamas posts in the Gaza Strip after a rocket fired from the Palestinian territory landed in a street in the southern Israeli town of Sderot on Wednesday, the Israeli military said.

Tall plumes of smoke from the Israeli strikes rose up from Gaza following the rare series of airstrikes during daylight. There were at least nine Israeli airstrikes on Hamas posts and open spaces throughout the Gaza Strip, according to Palestinian eyewitnesses, but there were no reports of injuries.

In Israel, no one was wounded by the rocket fire, but it marked an unusual incident of rocket fire penetrating Israel’s aerial defense system. Only a handful of projectiles have struck the previously battered town since the conclusion of a 50-day war between Israel and Gaza militants in the summer of 2014. Sirens wailed in Sderot warning of the incoming rocket, which landed near a school.
